Description

Technical Field

[0001] This utility model relates to the field of heating, ventilation and air conditioning (HVAC) engineering technology, specifically to an HVAC pipe. Background Technology

[0002] Heating, ventilation and air conditioning engineering includes heating, ventilation and air conditioning. Heating is the process of supplying load to a building as needed to ensure that the indoor temperature is consistently higher than the outside environment as required by people. Ventilation is the process of sending air into or out of a room.

[0003] However, in the existing HVAC duct installation process, multiple bolts and flanges are usually used to achieve a stable connection between two HVAC ducts. Since a large number of bolts need to be turned at once, workers need to tighten each bolt individually and install multiple HVAC ducts, which increases the workload of the workers. At the same time, the installation and stability of HVAC ducts cannot be separated from the auxiliary role of support blocks. These support blocks are fixed in the predetermined position by bolts. Due to the continuous interaction between hot and cold air inside the HVAC ducts, water molecules are generated. Water molecules are easy to condense and adhere to bolts and other metal parts, which can lead to bolt rusting and reduce the stability of the HVAC ducts. Utility Model Content

[0004] The purpose of this utility model is to provide a heating, ventilation and air conditioning pipe to solve the problems mentioned in the background art.

A threaded rod 7 is disposed within the inner cavity of the first mounting shell 3, and under the action of the rotating mechanism 6, multiple threaded rods 7 can rotate simultaneously on one side of the first mounting shell 3. A nut 8 is fixedly connected to the inner cavity of the second mounting shell 4, and the inner cavity of the nut 8 is threadedly connected to the surface of the threaded rod 7. With the cooperation of the threaded rod 7 and the nut 8, the first mounting shell 3 and the second mounting shell 4 can be connected to each other, which facilitates the installation of the first HVAC pipe 1 and the second HVAC pipe 2 by the workers, speeds up the installation of the first HVAC pipe 1 and the second HVAC pipe 2, and reduces the workload of the workers. A fixing plate 9 is installed on the surface of the first HVAC pipe 1, and a moving block 10 is slidably connected to the surface of the fixing plate 9. A protective shell 11 is fixedly connected to the bottom of the moving block 10. Under the action of the protective shell 11, the threaded rod of the fixing plate 9 can be protected, which can effectively reduce the occurrence of rust and wear of the threaded rod, thereby improving the stability of the fixing plate 9 during operation. A fixing block 12 is fixedly connected to the surface of the fixing plate 9. A limit mechanism 13 is provided on one side of the fixing block 12. With the cooperation of the fixing block 12 and the limit mechanism 13, the protective shell 11 can be limited by the moving block 10, which facilitates the installation of the threaded rod of the fixing plate 9 by the workers, thereby reducing the workload of the workers.

[0023] The rotating mechanism 6 includes a first gear ring 61, one side of which meshes with the surface of a bevel gear 5, and a second gear ring 62 is fixedly connected to the other side of the first gear ring 61. A spur gear 63 meshes with the surface of the second gear ring 62, and one side of the spur gear 63 is fixedly connected to one end of a threaded rod 7. There are multiple spur gears 63, and the number of spur gears 63 corresponds to the number of threaded rods 7. Under the action of the bevel gear 5, the first gear ring 61 can drive the second gear ring 62 to rotate in the inner cavity of the first mounting shell 3. The second gear ring 62 drives multiple spur gears 63 to rotate simultaneously. The spur gears 63 drive the threaded rod 7 to rotate, and with the cooperation of the nut 8, the first mounting shell 3 and the second mounting shell 4 can be installed, which facilitates the installation of the first HVAC pipe 1 and the second HVAC pipe 2 by the workers, speeds up the installation of the first HVAC pipe 1 and the second HVAC pipe 2, and reduces the workload of the workers.

[0024] The limiting mechanism 13 includes a manual disc 131 disposed on one side of the fixed block 12. A tension spring 132 is fixedly connected to one side of the manual disc 131, and the other side of the tension spring 132 is fixedly connected to the surface of the fixed block 12. A limiting rod 133 is fixedly connected to one side of the manual disc 131. The surface of the limiting rod 133 is slidably connected to the inner cavity on one side of the moving block 10. The surface of the manual disc 131 has multiple grooves. Under the action of the manual disc 131, the tension spring 132 can be stretched on one side of the fixed block 12. With the cooperation of the limiting rod 133, the protective shell 11 can be limited to one side of the fixed plate 9 by the moving block 10, thereby facilitating the installation of the screw of the fixed plate 9 by the operator.

[0025] Working principle: When workers need to connect and install the first HVAC pipe 1 and the second HVAC pipe 2, they use tools to rotate the bevel gear 5 inside the first mounting shell 3. The bevel gear 5 rotates the second gear ring 62 through the first gear ring 61. The second gear ring 62 drives multiple threaded rods 7 to rotate simultaneously. With the cooperation of the nut 8, the first mounting shell 3 and the second mounting shell 4 can be connected and installed together, thus connecting the first HVAC pipe 1 and the second HVAC pipe 2. When workers install the fixing plate 9 through the screw, they move the protective shell 11 upward through the moving block 10. At the same time, under the action of the manual disc 131, the tension spring can be... Spring 132 is stretched on one side of fixed block 12. Manual disc 131 drives limit rod 133 to intersect with one side of moving block 10. When moving block 10 moves to the corresponding position, under the action of the rebound force of tension spring 132, manual disc 131 can drive limit rod 133 to move to the inner cavity of one side of moving block 10. Then, the operator installs fixed plate 9 through screw rod. After the fixed plate 9 provides auxiliary support for the first HVAC pipe 1, the operator makes limit rod 133 intersect with one side of moving block 10. Moving block 10 drives protective shell 11 to move downward back to the original position, so that protective shell 11 can protect screw rod. Then the first HVAC pipe 1 and the second HVAC pipe 2 can work.
